System Requirements; Xenserver* Host System Requirements; Xencenter* Requirements - Intel S3420GP Installation Manual

System Requirements

XenServer* requires at least two separate physical x86 computers:
One to be the XenServer* host.

One to run the XenCenter* application.

The XenServer host machine is dedicated to the task of hosting VMs and is not used for other
applications. The computer that runs XenCenter can be any general-purpose Windows* computer with
the hardware requirements, and can be used to run other applications simultaneously.

XenServer* Host System Requirements

The XenServer* host is a 64-bit, x86 server-class machine devoted to hosting multiple VMs. This
machine runs a stripped-down Linux* operating system with a Xen*-enabled kernel that controls the
interaction between the virtualized devices seen by VMs and the physical hardware. The following are
the system requirements for the XenServer host:
One or more 64-bit x86 CPU(s), 1.5 GHz minimum, 2 GHz or faster multicore CPU
recommended
To support VMs running Windows*, an Intel® VT 64-bit x86-based system with one or more
(up to 32) CPUs is required
CPUs
Note: To run Windows* VMs, hardware support for virtualization must be enabled on the
XenServer* host. This is an option in the BIOS. It is possible the system BIOS might have
virtualization support disabled. Consult BIOS documentation for more
To support VMs running supported paravirtualized Linux*, a standard 64-bit x86-based
system with one or more (up to 32) CPUs is required.
1 GB minimum; 2 GB or more recommended.
RAM
Locally attached storage SATA, SAS with 16 GB of disk space minimum.
60 GB of disk space recommended
General disk space requirements for VMs:

Disk Space



100 Mbit/s or faster network interface card (NIC). A gigabit NIC is recommended for faster
Network
P2V and export/import data transfers and for live relocation of VMs.

XenCenter* Requirements

The remote XenCenter* application for managing the XenServer* host can be installed and run on any
Windows* 2003*, Windows XP*, Windows Vista* workstation or laptop.
The following are the system requirements for XenCenter*:
.
Product installation creates two 4GB partitions for the XenServer* host control domain;
the remaining space is available for VMs:
VMs based on the Debian* templates are allocated a 4 GB root device, and a 512 MB
swap device.
Linux* VMs are allocated an 8 GB root device.
Windows* Vista* VMs are allocated a 16 GB root device; other Windows VMs default
to 8 GB.
